here's what I'd like to see processor..
11.3 channel support
adequate chassis height, enough space between components
10 hdmi inputs
3-4 hdmi output
10-12 spdif digital optical
3spdif output
10 component input
3 component output
10 s-video in
3 s-video output
composite optional 1in/1out
10 rihd inputs
12-16 port network switch with a min of 4 port dedicated to dl-4 (denon link 4 type interface support) with proper port associations with option of adding a second switch in.
11.3 balanced and unbalanced with dip switch selector..
2-3 7.1-9.3 zones 2/3/4 with unbal/balanced to secondary receivers/processors
dab/sat radio, and iptv support
phono and tape support
twin power supply on hotswap

if going a OS route i would look a ssd option for hard drive use and usb for keyboard and mouse

side note: the reason I was suggesting the option of adding the network switch with the option of expansion because sometimes space within a area is a premium you can't always add in a network switch to cater for all the network compatible consoles and various other network detached devices, it would be nice to have a network switch built in for a change..
